From 5a55c2596f55e3a60f7502d0dfcfa0d20241e5ac Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Thu, 16 Nov 2006 19:24:13 +0900 Subject: [SCSI] scsi tgt: scsi target lib functionality The core scsi target lib functions. TODO: - mv md/dm-bio-list.h to linux/bio-list.h so md and us do not have to do that weird include. - convert scsi_tgt_cmd's work struct to James's execute code. And try to kill our scsi_tgt_cmd. - add host state checking. We do refcouting so hotplug is partially supported, but we need to add state checking to make it easier on the LLD.
